RUN Mode, Scientific Notation, Normal Operation

Scientific Notation

The Model 2002 measures pressure that spans more than seven decades. In order to easily display these readings, Hastings Instruments has employed scientific notation. In scientific notation, the mantissa (the fixed point part) is multiplied by some power of 10 (given by the exponent).

	Powers of 10
103	= 1000	10-1	= 0.1
102	= 100	10-2	= 0.01
101	= 10	10-3	= 0.001
100	= 1	10-4	= 0.0001

As an example: 7.60 x 10+2 Torr

{

Mantissa exponent

"7.60 multiplied by 100" = 760 Torr which is one atmosphere of pressure.

3.2.RUN Mode

Normal Operation

The Model 2002 will automatically enter RUN mode upon start-up. This is the mode for normal operation and the mode in which the instrument will typically spend most of its time. In the run mode, the Model 2002 unit will continuously monitor the pressure and update the alarm conditions at the speed of the A/D converter and will update the display about four times per second.

A/D Speed Adjust

The Model 2002 utilizes a 24 bit sigma-delta analog to digital converter. This type of converter averages the input over time to reject interference. Longer averaging times result in more accurate readings. Increasing the A/D speed will respond to sudden pressure changes faster.

While in the RUN mode, the user can adjust the A/D speed of operation. At start-up, the instrument will be operating with an A/D frequency of about 60 Hz. The speed can be adjusted one step faster or slower. Each step will increase or decrease the A/D frequency by a factor of two.

To adjust the A/D speed, press the MODE switch until the RUN light is illuminated. Then simultaneously press the up and down switches. The RUN light will now flash indicating that the interlock has been bypassed and the A/D speed can be adjusted. Push the up switch to speed up the A/D converter one step and decrease the response time. This will result in a faster triggering of alarms or relays if a sudden catastrophic failure occurs. Pressing the switch after the limit is reached has no effect.

Pushing the down switch will slow down the A/D converter and increase its accuracy. This will improve the ability to resolve low pressure readings. If a certain speed is desired, press the UP or DOWN switch three times and then press the other switch to select the other speed.

On older units. There will be no indication of the operating speed other than the least significant digits of the display will tend to run at higher speeds. On units with software version 1.60 and above, press the ZERO switch to display the decimation ratio (filtering). The larger the ratio, the longer the response time.

EEPROM Calibration Restoration

There are interlocks built into the CAL mode to minimize the chance of accidental alteration of the calibration coefficients, but if calibration alteration does occur, the EEPROM calibration data can be restored in the RUN mode by pressing the UP and DOWN switches simultaneously (RUN light will flash), then press the “ZERO” switch, UP and DOWN switches (all three) simultaneously.
